In this road traffic accident case where there was a claim for psychiatric injury, the two psychiatric experts produced between them 14 reports, including addenda and other admissible communications. The fundamental disagreement was the diagnosis: PTSD or adjustment disorder. It appears that four of the reports by the defendant’s expert were in rebuttal of the opinion of the plaintiff’s expert. This summary does not reflect the considerable extent to which the court had to analyse the evidence as to diagnosis. In the court’s judgment diagnosis hardly mattered. The judge said that more important, in his view, was the impact that the condition had on the plaintiff’s everyday functioning and lifestyle. Then when awarding damages, he said that the psychiatric damage suffered by the plaintiff attributable to the accident could be described as moderately severe whether that be under a diagnosis of post-traumatic stress disorder or psychiatric damage generally. 

This is primarily a case for cardiologists, cardiac nurses and anaesthetists with a learning point for psychiatric experts. Viewed from outside the jurisdiction the striking feature of the case is that the plaintiff’s general practitioner records documenting a previous psychiatric history, which she had denied when assessed by the two psychiatric experts, were not disclosed to the defendant until five days into the trial.
